Reconstructing effective Hamiltonians from nonequilibrium (pre-)thermal steady states
Sourav Nandy, Markus Schmitt, Marin Bukov +1
Reconstructing Hamiltonians from local measurements is key to enabling reliable quantum simulation: both validating the implemented model, and identifying any left-over terms with…
Weak universality, quantum many-body scars and anomalous infinite-temperature autocorrelations in a one-dimensional spin model with duality
Adithi Udupa, Samudra Sur, Sourav Nandy +2
We study a one-dimensional spin- model with three-spin interactions and a transverse magnetic field . The model has a symmetry, and a duality between a…
Quantum state complexity meets many-body scars
Sourav Nandy, Bhaskar Mukherjee, Arpan Bhattacharyya +1
Scar eigenstates in a many-body system refers to a small subset of non-thermal finite energy density eigenstates embedded into an otherwise thermal spectrum. This novel non-thermal…
Spin-1/2 XXZ chain coupled to two Lindblad baths: Constructing nonequilibrium steady states from equilibrium correlation functions
Tjark Heitmann, Jonas Richter, Fengping Jin +7
State-of-the-art approaches to extract transport coefficients of many-body quantum systems broadly fall into two categories: (i) they target the linear-response regime in terms of…
